WebMagnetic resonance spectroscopy (MRS) is an imaging technique used to measure brain metabolism [ 47]. It is popular in IEMs for monitoring of disease progression and therapeutic response. MRS is noninvasive. Its use allows one to gain information relevant to tissue biochemistry and metabolism [ 48].
